Original job description

The vision of the Product Knowledge Ontology Team is to provide a standardized, semantically rich, easily discoverable, extensible, and universally applicable body of product knowledge that can be consistently utilized across customer shopping experiences, selling partner listing experiences and internal enrichment of product data. We aim to make product knowledge compelling, easy to use, and feature rich. Our work to build comprehensive product knowledge allows us to semantically understand a customer’s intent – whether that is a shopping mission or a seller offering products. We strive to make these experiences more intuitive for all customers.

Proven skills in data retrieval and data research techniques
Ability to quickly understand complex processes and communicate them in simple language
Ability to communicate knowledge-based requirements and needs to engineering and retail teams
Familiarity with Semantic Web technologies (RDF/s, OWL), query languages (SPARQL) and validation/reasoning standards (SHACL, SPIN)
Detail-oriented problem-solving, ability to work in fast-changing environment and manage ambiguity
Proven track record of strong communication and interpersonal skills Preferred qualifications
Master’s degree in Library Science, Information Systems, Linguistics or other relevant fields
Experience building data models in the e-commerce and semantic search spaces
